Abstract: A packaging body is configured from a main body which comprises a sheet member and is formed with an accommodation space communicating with an opening formed inside, and with a lid which can open and close the opening. In this packaging body, a wet sheet accommodated in the accommodation space can be removed through the opening. The main body is formed extending in a first direction. Furthermore, the main body has a suspension hole for holding the main body formed in a region at one end in the first direction. The lid has a base portion adhered to the main body, and an opening and closing portion configured so as to connect with the base portion and be peelable relative to the main body. The opening and closing unit is connected to one end portion from the base portion in the first direction. Between at least the opening and the suspension hole in the first direction, a reinforcing sheet for reinforcing the main body is formed in the main body.

Abstract: A packaging body is configured having a main body which is made of a sheet member and which comprises an internally formed accommodation space communicating with an opening, and a lid, which can open and close the opening. In this packaging body, wet sheets accommodated in the accommodation space can be removed through the opening. The main body is formed extending in a first direction. Furthermore, the main body has a suspension hole which is for holding the main body and is formed in a region at one end in the first direction. The lid has a base portion adhered to the main body, and an opening and closing portion configured so as to connect with the base portion and be peelable relative to the main body. The main body comprises a fixing region where the base portion is fixed, a peeling region where the opening and closing portion is adhered through an adhesive, and an opening forming region where an opening is arranged surrounded entirely by the fixing region and the peeling region.
